4. An automatic valve comprising a Casing having an inlet and an outlet, a valve controlling the passage between said inlet and outlet, closing meanstending to move said valve to its closed position, pressure operated means adapted to dominate said vfirst means for maintaining said valve in its open position, a toggle connection between .said means adapted to be automatically tripped when said pressure operated means fails as said valve is moved to its closed posit-ion and a setting lever whereby said toggle connection may belmanually returned to its operative positionl and the rigidity of the connection between said means is thereby restored.

5. An automatic valve comprising a casing having an inlet and an outlet, a/ valve in said easing controlling the passage between said inlet and outlet, a support mounted upon said Ieasing, a valve stem carrying said valve and slidably mounted upon said support, a spring tending to adjust said valve to one of its positions, a operated diaphragm normally dominating said spring to adjust said valve to aicontrary position. a bar controlled by said diaphragm, a toggle connection between said bar and stem, means for tripping said toggle connection when said pressure operated diaphragm fails to dominate sa d spring and said valve is thereby automatically adjusted ite-said `one of its' positions and a setting lever `for manually re-setting said toggle ronneotionto restore the operative connection between said bar and stem` 6. lhe combination of an oil burner, a pipeline for an atomizing agent under pressure leading to said burner, an oil line leading to said burner, a valve in said oil line, means tending to move said valve to its closed position, pressure operated means normally dominating said first means to maintain said valve in an open position, a connection between said two means adapted to normally transmit the action of said pressure means to said valve and to be tripped when the pressure fails and said valve is automatically adjusted to its closed position' to shut oit the supply off oil to said burner and means whereby said connection 'is manually re-set when vsaid pressure has 'gle connection between said valve and dia phragm, means for tripping said toggle eenneetion'when said pressure fails and the valve is thereby automatically adjusted to its closed position to shut off the supply oit' oil to said burner and a setting lever for manually re-setting said toggle connection to restore the operative connection betweensaid diaphragm and valve whereby the latter is returned te its openposition when said pressure is restored. v
